Ah, yes.
Alien Leader: Ok, we've got all of this advanced technology, & we've been planning this invasion for hundreds of years. How should we carry it out?
Alien: Uhhh.. I think we should... ummm... blow them up while we have the chance. *gets vaporized*
Alien Leader: MORON!!! Anybody else?
Other Alien: We should kidnap them one by one, but we can't take anybody that's actually important. We should leave the Nyquil behind too, we won't be needing that.
Alien Leader: PROMOTION FOR YOU!!!!!

Well, one movie that I thought kinda had a sucky ending was Open Water. I dunno how many people have seen that here, tho. The ending to Freddy vs Jason blew. "Ohhh, Freddy's dead. Oops, no he's not. "
